    Default Finally, the Mill has come home.

    Finally have a Milling machine, courtesy of John.
    //metalworkforums.com/f223/t200...illing-machine
    Picked it up last Saturday with a friend and his 8X5 trailer, got it home today Sunday, as he lives in Adelaide during the week, and comes home on the weekends.
    Had to get an engine crane to do the heavy work, thought about hiring one, $50 for the day, I'd need to hire it several times to assemble and move the mill, plus the shaper and Hercus lathe, that are still to come. It's sitting under the carport at the moment, till I can get the shed finished. SWMBO asked "Why did I get it now?", told her "John wanted it out of the way as he's going away", "that's his problem not yours" was the reply, some women just don't understand!!!!!
    Now the fun begins, working out what goes where, as it's in about 100 pieces, at least I'll know what makes it all work?

    For those that can't follow the link, here are some pics of it assembled.

    Would I be better off leaving it with the 3 phase motors and VFD, or swapping them over for single phase?
    I don't really understand the electrics of converting single phase to 3 phase or setting the parameters, I think they're called.
    If I go with the VFD, what do I stay away from, or watch out for, and what is a good brand to get, that is simple to use?
    Can one unit be fitted with a socket and then swapped over for another machines use?
    Sorry for all the questions, but I'm confused by it all.
    Thanks,
    Kryn

    More like mother and daughter.
    I think it's a common trait in Women, they don't like to see a bloke with more toys than them!!!

    My last two machines I bought involved a road trip to Sydney to pick them up. I'm at the stage now that if I told my wife I was going to Perth to pick up a machine, she would just roll her eyes with a smile and tell me I'm out of control!

    She knows she can't really complain. I could be doing alot worse. I build and fix just about everything around the house and I logbook service both the family cars on top of working on average 50 hours a week.

    I earn my keep!

    Is that a brown and sharpe taper in the horizontal spindle? Universal table machines can be extremely useful. Did you get much tooling?

    My wife often says it would cost us a fortune if I couldn't make or repair the things I do, most blokes just aren't that handy.

    Fortunately this machine was only about 70kms away, but I know what you're talking about Simon, I need to get to Sydney to pick up my Surface Grinder!!!!
    I think the taper is a number 3 Morse taper, according to John, we'll see when I get around to assembling it, hopefully this weekend, as SWMBO is complaining about the JUNK???? under the carport.
    It would cost me a fortune also, plus our rent would go up astronomically as I do the maintenance work as required for the landlord. I have a friend that's not handy, a weekend farmer, and I'm regularly asked to fix stuff for him. Even had to do Gyprock and timber work for him.
    Thanks everyone for the likes and comments.

    Not in my opinion;you'll get variable speed with a vfd. You may still need to change belts occasionally.
    You'll also need to sort out coolant pumps, lights, and maybe power feed
    But you'd have to do all that anyway, if you converted to single phase.

    I don't really understand the electrics of converting single phase to 3 phase or setting the parameters, I think they're called.
    That is a challenge. A better known brand will increase the odds that someone has been there before..
    The motor also needs to be capable of 240 Y rather than 415 Delta. (or is it the other way around?)
    If I go with the VFD, what do I stay away from, or watch out for, and what is a good brand to get, that is simple to use?
    Powtran.

    Can one unit be fitted with a socket and then swapped over for another machines use?
    Technically, yes. Some vfds support multiple sets of parameters. But three phase plugs and sockets aren't cheap. I wouldn't plan on it.

    The other way would be a 3 phase converter, most likely some sort of rotary converter, which could be used for multiple machines.

    I'm sure someone more knowledgeable will be along soon..

    I have a couple of machines that have multiple 3 phase motors as part of their operation and in order to keep the VFV conversion economical, I run more than one motor on the VFD as once.

    For instance, my surface grinder runs a spindle motor, hydraulic pump motor and coolant pump. I run all on the one VFD. The setup is simplified to an extent because I don't deviate from 50Hz and so all the motors are running at the "correct" single speed.

    With a mill, you will want to capitalise on the variable speed of the VFD, so if you decide to run the spindle AND say a coolant pump from the same VFD (at the same time) then the coolant pump will change in speed too. Probably not a big deal if you keep the speed range "reasonable" but at the speed extremes the coolant pump will either not work (low speeds) or may be pushed into cavitation at high speeds.

    Another example, I have in the past run my shaper from the VFD on my mill. Both motors are 3 HP and the parrameter setup on the VFD is not particularly complex so it works OK. However, the controls for the VFD are on the mill (as you would expect) and so this can be inconvenient at best and down right dangerous at worst if the controls are out of reach during operation.

    Any chance of a pic of how you've got the VFD set up on the mill, please? Chasing up prices on VFD's now.
    Thanks,

    Hi Kryn,

    You need to connect the motor configuration to Delta (.ie the triangle). Open the terminal box, if you see 6 terminals then its easy to do but it there is only 3 wires coming out then you will have to open it up to disconnect the star connection and bring the other 3 ends out for the delta configuration.

    I am using this on the Hercus lathe and knee milling machine and so far so good. From memory I paid around $150 each but that is a while ago. You can change the motor speed by turning the knob to adjust the output frequencies, anything under 20hz is almost unusable as there isn't enough torque to turn. I think if you get a "vector" vfd it will be usable through the range but it's expensive, I think I saw a thread with product/link under "electrical" section, not long ago about it.

    I used the ribbon cable to extend the control panel and mount the main unit on the wall. I think this one http://www.altronics.com.au/p/w2610-10-wire-idc-cable/

    The motor I have on the mill is star configuration, I had to bring the ends out to reconnect into delta for VFD. Just to give an idea

    The motor has already been converted, as John the previous owner has used it on a VFD, just a matter of getting one, and wiring/setting it up.
